Martino, North Brunswick, NJ assignor to Syncro Machine Company, Perth Amboy, N.J., a corporation of New Jersey Filed May 31, 1960, Ser. No. 32,894 6 Claims. (Cl. 242-25) This invention relates to machines for coiling or reeling wire and particularly to a mechanism by means of which the initial and therefore usually unprocessed damaged or unusable end of a long length of wire to be coiled or reeled may be segregated from the remainder of the wire during such coiling or reeling whereby it may readily be disposed of.

in Patent No. 2,341,369 issued to C. M. Fornwald, Jr. and assigned to the assignee of this application, one mechanism for eliminating such unusable wire ends is disclosed. The present invention provides a simpler mechanism than that of the above-mentioned patent, while performing the wire end eliminating function equally end of wire to be coiled or reeled may be segregated, so that it may readily be discarded subsequent to coiling or reeling.

It is another object of the-invention to provide such a mechanism which requires very little modification of the coiling mechanism.

Qther objects and features of the invention will be apparent when the following description is considered in connection with the annexed drawings, in which,

FIGURE 1 is a side elevational view of the spool end of a coiling machine showing a portion of the wire distributing mechanism modified in accordance with my invention; and

FIGURE 2 is a front elevational view of the spools and distributing mechanism as depicted in FIGURE 1.

As discussed in the above-mentioned patent, after wire has been processed as for example by coating, it is wound on spools or into reels for handling and transportation. Generally, however, the initial end of the wire, due to threading of the coating machine, has not been processed and may also have been damaged. Similarly, wire which has been annealed generally has an end which, due to the threading of the annealing machine, has not been annealed and therefore is a hard end which should be discarded. It is therefore desirable that the damaged end be segregrated from the remainder of the wire while on the spool so that the discarding thereof is possible before the wire is shipped. Thus all of the wire on the shipping spool is undamaged.

In order to accomplish the result set forth above an auxiliary spool is provided and the leading end of the wire is wound on this spool. After the damaged portion has thus been wound on the auxiliary spool, the wire is guided from the auxiliary spool to the main spool. Thus when the winding of the main spool has been completed and that spool is to be removed from the mandrel, the beginning end of the wire on that main spool may be severed from the damaged wire on the auxiliary spool and dependent upon the length of wire wound on the auxiliary spool, if desirable a length of undamaged wire may be left exposed thus facilitating certain operations such as the welding of the beginning end of wire on the spool (which will of course be the terminal end when the wire is unwound) to the end of another spool when successive spools are being used as a continuous length.

Referring now to the drawings, there is shown at 10 a portion of a spooling or coiling machine from which projects a power driven mandrel 11 upon which the main spool 12 is mounted. Also mounted on the mandrel 11 is the wire end or auxiliary spool 13. This spool 13 is formed of a cylindrical portion 14 and a frusto-conical portion 15 and has at its outer or left hand end a disk 16. Disk 16 may be integral with or fixed to the spool 13. It may, if desired however, be a separate part interposed between the flange of spool 12 and the end of spool 13.

Mounted upon the conical surface 15 are a pair of clips 17 spaced apart. These clips are utilized to hold the end of a wire length during the coiling on the auxiliary spool. Two clips are provided merely as a matter of convenience, it being obvious that one is all that is necessary.

ln'FIGURES 1 and 2 there is shown above the reel 12 a portion of the usual wire distributing mechanism which operates in the usual manner to wind even layers of wire on the spool or reel 12. This distributor comprises the arm 18 which reciprocates on the rods 20 and which carries the rods 21 on which the wire guiding block 22 is freely slidable. The wire is guided through the block 22 by means of the aperture 23 formed therein. In the present instance block 22 has been modified by providing the arm 24 which arm extends toward the auxiliary spool, that is, to the right as shown in FIGURE 2. Arm 24 in turn has a pin 25 extending therefrom. This pin serves as an auxiliary wire guide during the reeling of the wire end upon the auxiliary spool 13. The wire is therefore, when the machine is threaded, led first through the wire guiding block 22 and thence over the pin 25 and clipped in one of the clips 17. This position of the wire is that shown in full lines in FIGURE 2. The mandrel 11 is then caused to rotate in the usual manner and Wire is wound upon the cylindrical portion 14 of the auxiliary spool 13. When suflicient wire has been wound upon this spool the operator engages the distributor mechanism thus causing the block 22 to travel toward, the left as seen in FIGURE 2. As a result, the pin 26 fixed in the periphery of disk 16 and extending to the right will engage the reach of wire between pin 25 and spool 13. As will be obvious, this engagement of the pin will, as the mandrel and spools rotate, cause the wire to move to the right as seen in FIGURE 1, disengaging the wire from the pin and permitting the wire to feed directly from the block 22 to the main spool 12 passing, of course, over the right hand flange of the main reel '12.

As the distributor continues to operate in its normal manner it will reciprocate through a distance equal to the distance between the flanges of the main spool and will wind layers of wire on the main spool. The pin 25 will play no part in the winding subsequent to the removal of the wire therefrom by action of the pin or screw 26 as above described.

When the winding of the main reel is completed, the main reel is removed from the mandrel and the wire is cut at some point between the periphery of the reel flange and the portion coiled upon the auxiliary spool, the length of wire remaining on the mainspool being that desired but including no portion of the damaged or uncoated or untreated end.

While I have described a preferred embodiment of the invention, it will be understood that I wish to be limited not by the foregoing description, but solely by the claims granted to me.
